Sharp Notes
Image sharpness has a special button!
Actually, these 'buttons' are organ mixture stops. These stops give to each organ note simultaneously the notes of the major chord, in other words the major third and perfect fifth. Some say that arguably, in some cases these stops result in harmonic congestion as they are largely a result of medieval ignorance and their search for loudness in a world without electricity to drive power amplifiers. Organs were at one time talked of as 'instruments of power', as mixtures were used to achieve a balance of harmony and acoustic power resulting in loudness across an audio spectrum, something that played a significant part in medieval power politics.
